The small amount of yeast residue in the bottle is due to
krausening, according to SN. However, the wort used for krausening
could be alive with lager yeast, for all one knows. Perhaps the
viability of the yeast could depend on the history of the bottles
you mentioned. See Homebrew Digest #227 for a comment on the age
of bottled beer and an attempt at culturing Chimay yeast.
